The Rebellion of the Seven States was a significant conflict during the early years of the Han Dynasty in ancient China, occurring around 154 BCE. It arose when seven regional states revolted against the central authority of the Han government, primarily due to dissatisfaction with heavy taxation and the centralization of power. The rebellion highlighted the tensions between the central government and local rulers. The conflict was ultimately suppressed by the Han forces, leading to a consolidation of power in the central government. Following the rebellion, the Han Dynasty implemented reforms to address the grievances of the regional states, aiming to prevent future uprisings and maintain stability across the empire.
